摘要：

The increased consumption of plastics in day to day life has a significant impact on the environment. Life cycle assessment (LCA) is widely used to select a sustainable alternative in plastic waste management. The LCA studies on mechanical recycling and energy recovery scenarios showed that recycling resulted in lower emissions and provided benefits to the environment. These results are valid only if the performance of the recycled plastic is equivalent to those of the virgin materials. Many LCA studies have been focused on individual impact categories rather than aggregated single score. The decision making process becomes complex if individual impact categories are used. This research is focused on the comparison of LCA results between individual and aggregated impacts and integration of performance of recycled plastics in LCA. The results indicated that recycling was the preferred option if it could replace a minimum of 70-80% of virgin plastics.
